Astroglial development as the basis for the effects of early life stress on adult depressive-like behavior
This thesis investigates the enduring effects of early-life stress, specifically maternal separation, on astroglial population and the subsequent behavioral outcomes in adult mice. While the persistent impact of early-life ... -
Characterization of Visual Stimulus-Induced Gamma Oscillations as Signatures of Mechanisms Underlying Healthy Aging and Disease
Neural oscillations are rhythmic fluctuations in the electrical activity recorded from the brain that convey important information about brain function. Gamma oscillations, which refer to the 30–80 Hz frequency range, are ... -
Comparative evaluation of retrograde regulatory proteins (Rtg1p, Rtg2p, and Rtg3p) of Saccharomyces cerevisiae and Pichia pastoris and identification of P. pastoris RtgXp as a novel regulator of multiple metabolic pathways
Our work demonstrates for the first time that PpRtgXp, a basic, helix-loop-helix (bHLH) protein, is a global regulator of carbon metabolism. PpRtgXp constitutively localizes inside the nucleus. Despite lacking the C-terminal ... -
Computational Investigation of Heterogeneous Lateral Organisation in Biological Membrane
The study of lateral heterogeneity on membrane surface has come a long way from the fluid mosaic model. Simulations and experimental studies have observed non-random mixing of lipids and proteins in the membrane. In this ... -
Decoding of Attention and Behavioral State Using Local Field Potentials
Visual attention has been shown to modulate perceptual behavior and neuronal activity. Early psychophysical studies on attention showed that the subjects detected a target presented at the attended location better (i.e., ... -
Design, Synthesis, and Bioactivity of Thioamidated Macrocyclic Peptides
The work presented in this thesis describes the comprehensive study related to thioamidated macrocyclic peptides. We study the underexplored class of peptide bond isostere; thioamides in the context of small macrocyclic ... -
Diversity and distribution of mixed-species foraging groups in the Lakshadweep Islands, India
Species interactions are known to shape biological communities. While antagonistic interactions like competition and predation are well known, cooperative interactions have received comparatively less attention. Mixed-species ... -
Effect of Stimulus Normalization and Visual Attention at multiple scales of Neural Integration
The effect of visual attention on neural signals has been extensively studied using various techniques such as macaque neurophysiology and human electro/magneto encephalogram (EEG/MEG). Depending on the technique, different ... -
Ground-dwelling arthropods across human land use: Interpreting the spatial and temporal dimensions of beta diversity
This study investigates beta diversity and its partitions to quantify the influence of different processes that drive spatial and temporal variation in ground-dwelling arthropod assemblages. First, ant assemblages across ... -
Insights into mRNA recruitment by eukaryotic initiation factor 4 during translation in Saccharomyces cerevisiae
Ribosomes are responsible for synthesizing proteins in the cells by using mRNA as the template. However, the ribosomes cannot perform this function without the help of other protein factors. Different factors are required ... -
Insights into the conformational stability & pharmacology of peptides through side chain and backbone modification
The first part of the work presented in the thesis deals with CH-pi interaction, which is a lesser-known non-covalent interaction in proteins. We identified several CH-pi donor-acceptor pairs involving amino acids side ... -
Investigating the mechanisms of cancer drug resistance
Clinical chemo-resistance has posed a challenge to scientists and clinicians since the development of chemotherapeutics as anticancer strategy. Mechanisms of drug resistance continue to be a subject investigation amongst ... -
Large Herbivore Dung Decomposition: Effects on Nutrient Cycling in a Tropical Forest of Southern India
Large herbivores can selectively feed on nutrient rich resources, resulting in regular deposition of high quality organic matter in the form of dung. In tropical forests such as in southern India it is estimated that large ... -
Network Heterogeneities, Intrinsic Plasticity and Decorrelation in the Dentate Gyrus
A central premise for research in neuroscience is to mechanistically decipher the physiological roles of the brain in effectuating learning and memory. The tripartite framework that is at the core of learning and memory ... -
Neural Correlates and Behavioral Underpinnings of Remote Memories during Systems Consolidation
Remote retrieval of declarative memories has been under investigation for a long time. After acquisition, long-term encoding of memories happens through crosstalk across multiple brain regions. Through systems consolidation, ... -
Parietal and prefrontal control of distinct components of attention
In this thesis, we investigate behavioural mechanisms and neural substrates of distinct components of endogenous spatial attention. Endogenous attention facilitates neural processing of the selected stimulus through one ... -
Post-transcriptional regulation of the tumor suppressor gene TSC1 and its relevance in Oral Squamous Cell Carcinoma
Oral cancer or oral squamous cell carcinoma (OSCC) is a subset of head and neck cancer (excluding non-melanoma skin cancer), with an estimated 354,864 new cases and 177,384 deaths reported annually. India accounts for 34% ... -
Protein-small molecule interactions: Structural insights and applications in computational drug discovery
Deviation from normal healthy conditions, termed as disease, can often be triggered due to the malfunctioning of proteins. Modulating the functions of proteins by administering therapeutic agents (drugs) may alleviate the ... -
Scanning mutagenesis studies of HIV-1 Env immunogenicity and structure
Human Immunodeficiency Virus type 1 (HIV-1) is the etiological agent of Acquired Immunodeficiency Syndrome (AIDS). AIDS is a global pandemic with 36.7 million people living with HIV-1 all over the world and approximately ... -
Solution structures and interaction studies of mycobacterial MazEF6 toxin-antitoxin system
Toxin-Antitoxin (TA) systems are stress response systems found on plasmids and chromosomes of bacteria and archaea. They are involved in important functions such as plasmid maintenance, programmed cell death, persister ...
